Sharks tagged by scientists

A curious example of an heterogenous network of animals, technologies and people is described in Telegraph:

"More than 70 white pointers have been tagged by scientists is Western Australia in a world first trial that will send beach lifesavers a text message when one of the predators swims close to the Perth shoreline. Wildlife officials and scientists will also receive the text or email warning when any of the tagged sharks move to within 500m of metropolitan beaches. The text messages will be triggered less than two minutes after a shark swims over any one of 18 acoustic seabed receivers.
(...)
The study is aimed at unlocking the secrets of shark migration patterns and how they relate to attacks on humans."

Why do I blog this? amazement towards the reconfiguration of "nature". What's next? a surfboard with shark-location awareness tools.
